Using Triple Link Suspension

Triple Link Suspension (TLS) provides suspension for the tractor front end using a hydro-pneumatic self-leveling system. TLS can operate simultaneously, yet independently of Load Depth Control and Hitch Dampening, if equipped. Hydraulic cylinders provide the front axle with vertical suspension movement using three accumulators to absorb shock loads.

TLS will self-level automatically whenever tractor speed exceeds 1.5 km/h (0.9 mph). With implement attached and hitch raised or lowered, TLS will self level when:

the engine is shut off and restarted or

the tractor ground speed reaches 1.5 km/h (0.9 mph) with engine running.

Stay clear of tractor on start-up because TLS will self-level up and down.

Check for adequate clearance with TLS system when attaching a front-mounted implement.

Use normal cold weather procedures during cold weather operation. TLS system may require extra time to function correctly. TLS system may not operate if system had not re-centered during the first 80 seconds of operation. Several restarts may be required before system can be enabled.

An extra heavy load has the potential to exceed capacity of TLS system, but not the capacity of the loader or amount of downward force on a blade. If the warning light comes on, stop the tractor, decrease the load, and restart the tractor to reactivate TLS system.

If a fault occurs in the leveling control, the "Service Alert" light and "Read Operator's Manual" light come on, stop the engine and restart the tractor. If the fault repeats, contact your John Deere Dealer.
